<p>PURPOSE:To eliminate a malfunction by detecting each ID on a sub-code during the reproducing operation, deciding whether the times each ID are being recorded are proper times or not and making the correction. CONSTITUTION:The measurement with an internal timer is started by a microcomputer at the detecting time of start IDs, and the times measured by the timer are compared with a specific length of the start ID at the time when the detection of start IDs is finished, and when it is shorter, a rewinding is made for the detected time portion to erase that start ID. When it is longer, the rewinding is made up to the specific length after the start IDs are started, then the operation is made in such a manner that the start IDs thereafter are erased. By this procedure, the IDs on the sub-code recorded on a tape can be all re-recorded to the proper time, then the malfunction is eliminated in the functions such as a research of target ID, and so on.</p> |
